How to check your electrical system

[Outlawracer]

I have replaced my stator and pulse coil. I have tried a brand new ignition box . I cant see any broken wires or shorts , but i am only using a test l;ight. So my next step is to use a multimeter and check for opens. I already bought a soldering kit to repair the already mangled wiring harness , but i would rather buy a new harness altogether. I just cant see spending $70.00 on some wires. Does anyone know where to get cheap harnesses or even the plugs to make a new harness? If anyone sees can think of something i am overlooking let me know , but there arent really any other components outside the wiring. thanks

When my 250r first quit running the first thing i bought was a new cdi box. It did the exact same thing as the other one still no power to the coil. Now with every other possible item being brand new , I went and got the exact same box back from the cycle shop. Now before even installing this, I am noticing some differances. The number on the actual plug is HA8 and underneath that number it has a CI-91. The old one has HB9 and underneath it has CF552. The box the new one came in has a part #on it . The number is 30410-HA8-003. Is this even the correct box? When I test continuity accross the main power" in" to the killswitch "out" on the box itself i have to reverse polarity from one box to the other for it to even read anything, and when it does read the resistance is around double for the old one ( 5.2 Mohms) . the new one reads around 2.5 M ohms .
the plug is exactly the same for both boxes.

Here's a wire schematic...

Thanks for the wiring info. It looks like my wiring was wrong to my cdi box. I wonder why it ever ran? Anyway I'll probably get another aftermarket box. Instead of buying the one from dennis kirk I will try to get the same one from C&D since they sponsor this site. So anyone got a good wiring harness for cheap?

supposedly the 86-87 cdi is different then 88-89

or it might be the 86 is different then 87-89 i forget but supposedly the bike wont run right with the wrong one?

this is off the top of my head so im not really positive but i do remeber reading something about it.

the coils are different too.

I just talked to a guy that says the cdi boxes are all the same as long as they have the same plug and number of prongs . He sold me one with a part number that does not match the part number for a 250 r . I really dont believe him that htey all interchange. one small test i did do was checking the kill to power in on the new box to the old one . Polarity is different and so is resistance , but the old box could be bad. Anyway I think in parts catalogs the oem box for 86-89 is the same part number , as well as the aftermarket one in dennis kirk. This guy also says wiring them wrong will fry your stator and other parts, is this true?
